SPECIFICATION forming` part of `Letters Patent No. 288,340dated November 18, 1883.

A Application filed May 31, 1883. (No model.) l"

To all whom t may concern.-

Be it known thatI, AUGUST KAEsrNER, of the city, county, and State of New York, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates especially to lamps employed for illuminating purposes, Iwherein hydrocarbon oil is consumed; and has for its object-the production of a device cheap and simple to construct, andwherein an extremelybrilliant iiameis obtained. l y

To attain the desired end my invention consists, essentially, in` an oilfount, either of metal or glass, having a perforation or passage through its center from aY drip and air cup, gupon which the fount is mounted,a portion of the air to support combustion reaching the burner through said passage. The wick is raised and lowered in the manner usually employed in lamps of the class to which my invention relates. In the top of the oil-fount is a-"depression around the wick-tube, a petticoat formed of a single piece with the air-deflecting plate surrounding the wick-tube, and being seated in said depression and `attached to the wick-regulating tube, which eX- tends nearly to the level of the top of thecentraldraft-tube. `This'petticoat is perforated in such a manner as to supply air to the burner in such quantities and at such locations as to insure the most perfect combustion. rIhe chimney is of the Argand type; but its lower enlargement is made much shorter than usual, and by the peculiar construction of the oil-pot and burner the oil is lifted but a-short distance, greatly aiding combustion. i

1 In the drawings, Figure l is a view in elevationof my improved lamp. Fig. 2 is a vertical central sectional view thereof, and Fig. 3 is a plan view of the top of the lamp.

Like letters of reference, wherever they occur, indicate corresponding parts in all the iigures.

A is the standard of the lamp, of any approved form5and B is the drip-cup located `E is a centraldraft-tube secured to the bottom of the lamp, and `passing upward through the wick-tube F, as plainly shown in Fig. 2.

G is a regulating-tube for the wick, located between tubes E vand F, a spiral, e, being formed upon tube E in the usual manner.

H is a petticoat and air-deflector formed in one piece, and perforated at h, i, and j, for the purpose of supplying air to support combustion. The petticoat is attached to `the wickregulating tube G in such manner asA to leave a passage for air at 7c. g I

L isa ring `forming a support for the chimney M, the raising and lowering of the wick being accomplished by turning the petticoat upon its seat.

,It will be seen that air is supplied to the flame through the central passage, serving to spread said flame, and also through the perforations 71,1', and j, and annular passage 7c, which insures a perfect combustion and keeps the flame steady, preventing flickering, and producing a fine and even illumination.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, isv In a lamp of the character herein speciiied, oil-fount 4C, having a depression, C, inits top, as set forth, central draft tube, E, wick-tube F, regulating-tube G, petticoat I'I, perforated at h, i, and j, and secured to tube G, leaving an annular passage, k, therebetween, the whole combined and arranged to operate substantially as and for the uses and purposes shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses. i i

AUGUST KAESTNER.
